Sand mill grinding balls have many choices according to the material. Many customers who make paints and coatings originally used glass beads and now plan to change to zirconia beads, but they don’t know how to choose the right one, nor do they know the effect after the change. Combining theory and practical application, we will compare the two types of balls:
1) The density of glass beads is 2.5g/cm3, and the density of 65% zirconia beads is 4.0g/cm3, and the density of 95% zirconia beads is 6.0 g/cm3. The greater the density, the greater the unit volume weight and the higher the grinding efficiency.
2) Compared with the toughness of glass beads and zirconia beads, glass beads are not as good as zirconia beads, and 65% zirconia beads are not as good as 95% zirconia beads. The greater the toughness, the less likely the beads are to break at high speed.
3) Compared with the wear of glass beads and zirconia beads, glass beads have the greatest wear and are not at the same level as zirconia beads. They also have the greatest impact on the quality of materials. For example, zirconia beads can only be used for grinding food-grade, cosmetics and pharmaceutical-grade materials.
4) Compared with glass beads, zirconia beads have a wider range of material sizes. The maximum size of zirconia beads 95 can be 40 mm and the minimum size can be 0.1mm.
5) The price is lower than that of glass beads, while the price of zirconia beads is much higher.
